Four conference tournament champions will be crowned this weekend, clinching trips to regionals (more on those later). For most of the other conferences, tournies begin in the middle of next week, so series in most leagues will be played from Thursday through Saturday this week. There is plenty on the line across the country in the regular-season finale for most teams, but let's focus on the clash between the two teams tied atop the standings in Conference USA.

Since Louisville's 2007 trip to Omaha in Dan McDonnell's first season as head coach, the Cardinals and St. John's have been fixtures in the top third of the Big East standings. The two teams have played plenty of important series over the last five years, but none bigger than this weekend's set in Louisville—the marquee weekend on the Big East calendar this season.

Two days after a frustrating loss at Mississippi State, Matt Snyder and Bobby Wahl were in high spirits and relaxed, cracking jokes on the field at Trustmark Park, where Mississippi had just shut out Southern Mississippi 3-0. Ole Miss isn't the type of team that is going to pout and fall into a prolonged funk after a dispiriting loss such as Sunday's in Starkville, when the Rebels out-hit the Bulldogs 8-2 but found a way to lose 4-2, dropping their third series in the last four weeks.

As we look ahead to Week 11, let's focus on a pair of mid-major upstarts—New Mexico State and Army—before we get to the week's premier showdown between Pac-12 powers UCLA and Stanford. We'll focus on the Cardinal, which has emerged from a midseason lull after being forced to do some lineup tinkering recently.

With five series between ranked opponents on the docket, Week Seven should be fun for college baseball fans. The week's marquee series pits a pair of top 10 clubs against each other, as No. 2 Stanford visits No. 8 Arizona. Like the Wildcats, Georgia and Southern Mississippi face big tests this weekend against conference opponents ranked in the top 10: Kentucky and Rice, respectively. One other thing Arizona, Georgia and Southern Miss have in common: each brought in a strong recruiting class that ranked among our Top 25 classes last fall, and each is relying upon precocious freshmen in key spots this spring. So we checked in with each program to see how their youngsters have adapted to Division I competition, and how each team has dealt with other key issues.

When Mississippi State and Louisiana State take the field for their Southeastern Conference opener on Friday, the Tigers will be able to play seven position players who started a combined 184 SEC games a year ago. Infielders Austin Nola and Tyler Hanover also started all 30 games in 2010 and most of LSU's games in 2009. Mississippi State will counter with a lineup that features two players with a grand total of 17 SEC starts between them. That experience gap adds a fascinating wrinkle to this weekend's showdown between two SEC West powers with loaded pitching staffs.<br/>
